I found on line a tute for a Triangular Thread Catcher from "Needling Things". Has anyone here made one and if so could you PLEASE tell me how to assemble the three triangles. I took the three triangle to class and ask the teacher and students to help me and NO ONE CAN FIGURE OUT HOW TO PUT THE "THING" TOGETHER. The tute is on "Needling Things". Thanks in advance. I'm sure it is a very simple thing.
